This is truly a fabulous mapping app... I downloaded the free one for BlackBerry OS 10 for my Z10, and it shows even the smallest trail routings through local parks in my Broadmead, Saanich BC neighbourhood! There are pedestrian and auto views, and others probably... I have not fully explored it all yet.

It started out on Android, the URLs for it and the info are below.

Be careful which map you download, somehow I got an all-Canada background map with the BC map I downloaded, and the download took 4 or 5 hours I think... even in our house with a very good WiFi network...

It's quite technical, the info and the webpages, and I don't understand it all, but I bet other users here will have a blast with this! There are various layers you can add... I bet you can get trail maps through all the major National and Provincial parks! This is a really great application for a smartphone...

The spelling is, for some reason, OsmAnd.... BlackBerry World did a search and found it, but I don't think it's listed on BBy World, I may be wrong... IT SHOULD BE!!!
